The main frame 7 carries atk its rear end an auxiliary frame 8. Theauxiliary frame is removably mounted upon the main frame as explained inmy co-pending application, Serial #565,732, filed June 3, 1922. Brieflythis mounting may be described as comprising the following structure:The main frame comprises longitudinally extending angle Vbars 9, at therear end ot' which, angle bars 10 of the auxiliary frame 8 are mountedby means of brackets 11 and suitable bolts 12. The forward end of themain frame ispivotally mounted on a tubular support 13 and is adapted tobe oscillated thereupon. v A shaft 14 carried by the forward end of themain frame has mounted on it a sprocket 15 engaged by a chain 1G drivenfrom the motor 17 mounted on the forward end of the main frame 7. Anendless conveyer belt 18 adapted to be driven from the shaft 141 extendslongitudinally of the main frame and the auxiliary frame, and its rearend extends about a shaft 19 carried by the auxiliary frame 8. The belt18 is removably mounted rabout the shafts 141- and 19, whereby varionstypes of belts may be employed with the conveyer niechanismV carried bythe main frame 7, and whereby various discharging ends or auxiliaryframes may be employed with the main frame. The motor 17 may be adjustedlongitudinally of the main frame 7 as is disclosed in my eo pendingapplication, whereby to adjust the tension of the conveyer belt 18. Achute 20 is adapted to.V receive ware from a bottle machine and todirect the Ware upon the belt 18. rIhe klower endv 21 of the chute 20curves toward therear of the frames whereby to discharge the ware uponthe belt in such position that the ware will extend lengthwise of theframe, and have its base disposed toward, the auxiliary frame 8.Adjacent the rear end of the main frame are mounted downwardly extendingstandards 22 which support at their lower end a platform 23.

A motor 24E mounted on the platform 23 carries a bevel gear 2 inengagement with a bevel gear 26 mounted on the upper end of a shaft 27extending thru the platform 23. rlfhe lower end ot' the shaft 27 carriesa gear 28 which engages an arcuate rack 29 carried by a verticallyadjustable channel.

bar 30. The platform carries rollers 311 which ride upon the channel '30and support the platform. The platform also carries a. reversing switch32 controlling the motor 24, which controlling switch has an arm adaptedto engage blocks 34 and 35 mounted.v onl the channel adjacent theopposite ends thereof. The bevel gear 26may be revolubly mounted on theshaft 27 and may carry pins 36 which may be engaged by a lug` 37mountedon the upper end ot the shaft 27, wherebyV to render the trametemporarily stationary at its opposite limits ot oscillation. Theplatform also carries contact arms 88 and 39 whereby to close circuitsembracing a motor 40 adapted to uctuate the leer conveyer 41. rllhecontact arms are adapted to engage cams 42 and 43 mounted on thechanneladjacent the opposite ends thereof, whereby to bring the cou-`tacts 44 and 45 carried by said contact arms into electricalcommunication withl contacts 46 and 47 carried by the platform. rllhecontacts 44, 45, 46 andy 47 are embraced in the circuit embracing themotor 49.V The standards 22, carry intermediate their ends, cross bars48, upon which is mounted a motor 49. The rear end of the shaft 59extending 'from the motor 49 is supported by a suitable bea-ring 51carried by a bracket 52 mounted on the main frame adjacent the rear andlower en d thereof'. rl-he bracket 52 carries adjacent its lower edge apivotally mounted lug` 53. The bracket also carries an electro- 'magnet54 adaptedto operate upon the lug .53, and to move the lug about vitspivotal mounting 55. A spring 56 yieldingly retains the lug in itsnormal position as shown in Fig. 2. The rear end ot the shaft carries adouble cam 57 having cam 'faces 58 and 59. Friction discs 199 arecarried by a collar G0 mounted on the slia'lt 50 and are adaptedtotransniit motion from the collar (i9 to the cani 57. rllhe collar G()is adapted to move with the shaft 50. The l.am has a hub 61 thru whichextends an axial bore accommodating the shaft 50 and Ytrom the rear endof which the shaft 50 extends. Viashers G2 carried' by the shaft 50 abutthe rear end ot the hub 61 andare held in engagement with the hub by thespring 63 mounted on the intermediate reduced portion 64 of the shatt-50. The rear reduced portion 65 ot the sha'tt 50 carries a nut (3Gagainst which the spring abuts. 'llhe cam carries a lug G7 adapted to beengaged by the pivotally :mountedb lug 5?, whereby the cam 57 isnormally restrained against movement with the shatt 50. lVhen theelectro magnet energized so as to more the lug 53 upon its pivotalmounting and to withdraw the rear end of the lug 53 from the path of thelug 67, the cam revolves with the shalt 50. The motor 49, the shaftl 50and the cam mounted on the shaft are adapted to remain upon the mainframe although the auxiliary trame disclosed herein, is removed and adifferent auxiliary frame, such as disclosed in my co-pendingapplication, is mounted upon the frame. The auxiliary frame disclosedherein carries guide rails 68 andr 69 which together with strips 121 and122 slidably support a block 79. The block 7 9 carries a roller 71 heldin yielding engagement upon the cam 'face 58 by a spring 72. Immediatelyto the front ol" the rails 68 and 69, there are mounted on the lowerangle bars 10l orf theA auxiliary frame 8, brackets 73v and 74. Thebrackets 7 3 and 74 have bores formed in them, the bores extending indiametric alignment with the shatt 59, and having reciprocally mountedwithin them rods 75 and 76carrying at their inner end rollers 77 and 7 8engaging upon the cani tace 59. r1`he outer ends et the rods arepivotally connected to the 'llorward ends of arms 110 and 111, whicharms are mounted at their rear ends upon vertical shafts 112 and 113.Brackets 81 and 82 mounted upon the upper and lower angle bars 10 ot theauxiliary trame form bearings for the vertical shafts 112 and 113. Arms79 and 80 have their forward ends connected to the upper ends of thevertical sha1-'ts 112 and 113, respectively. Springs 83 and 84 havetheir opposite ends mounted upon bracket 73 and rod 75, and bracket 74andy rod 7 6 respectively. A way 85 extends longitudinally of the mainand auxiliary frames and its side walls are defined-by bars 86 and 87extending longitudinally ofl the frames, and which are supported bysuitable brackets 88 and 89 adjustably mounted upon the upper angle barsof the trames. The rear ends ot' the arms 79 and 80 carry pivotallymounted depending plates 90. The plates are weighted as shown in Fig. 1.The plates carry at their upper ends a V[iiiger 92 adapted to make anelectricalcontact upon the contact 93 mounted on the arm 80. Thecontacts 92 and 953 are embraced in a circuit embracing the electromagnet 54. rlhe plates normally assume a position such that when a jar94 reaches the rearend of the conveyer belt 1S, and is lodged in apocket 950 formed between the plates and the engagement ot the ware on(the plates causes movement of' one of the'plates 90 about its pivotalVmounting and completes the circuit between the contacts 92-` and 93whereby to `energize the electro magnet and to cause the cam to movewith the shaft 59. [rs the block 7 Oris moved rearwardly by the cam 57,the motion ot' the bloclr istrnnsmitted to the jar. This is e'tiiectedby means of 'a screw rod 95 carried by the block and a plunger plate 96connected.

with the screw rod 95 by a link 97. The plunger plate 96 has its sideedges turned downwardly whereby to form flanges 98 whichV terminateimmediately above the upper face of a bearing plate 99 carried by thelower angle bars 10 of the auxiliaryV The ars are adapted to bedeposited directly upon that portion of the leer conveyer immediately infront of the leer face `105. 'Ihe plunger plate 96. is adapted to bereciprocated immediately above the leer conveyer whereby topush the jars94 thru an opening 104provided in the face 105 of It is customary toprovide leers withl doors 115 which are slidable and reciprocabletransversely of the leer conveyer, whereby to provide a leer opening inalignment with the conveyer comprising the main and auxiliary frames.The parts bear a relation such that immediately the electro` magnet 541is energized and the-cam begins to revolve, the arms 7 9 and 80 aremoved outwardlyA at their forward ends by means of the cam face 59whereby to withdraw the plates 90 from the path thru which the plungerplate 96 is adapted to carrypthe jar 94. Suitable members 118 and 119are provided whereby to` form a way extending longitudinally of theauxiliary frame, thru which way the plunger plate may be reciprocated.'lherear ends of the uppei'angle bars 10 carry brackets 110 and 117carrying guide members 118 and 119 respectively. The guide members areadapted to extend downwardly and in continuity with the sidev walls 86and 87 of the conveyer and to terminate in the pocket 95 therebyprecluding the jars 9e from falling upon their sides. The guide membershave slots 120 thru which the plates 90 may pass.

vThe operation of my device is as lows: v v

lfoi- TvVare is delivered to the belt 18 from a.V

bottle machine by way of a chute 20 as previously explained. When theware reaches the rear end of they belt 18, the ware is disposed in thepocket 950 thereby engaging the plates 90 enclosing the 'circuits thruthe contacts 92 and 93. When the electro magnet 54 is energized, the lugis disengaged from the lug G7 and the move` ment of the cam 57 serves towithdraw the plates 90 from their normal position whereupon the plungerplate projects the jar thru the leer door opening 104. When the framescarrying the belt lreach either of their lateral limits the closing ofthe circuits thru the contacts carried by the channel bar and theplatform k23 serves to actuate the leer conveyer motor, and theengagement of the reversing switch armk upon the blocks carried by thechannel :bar reverses the direction of the movement of-the frames aboutthe support 13. As soon as the plates have moved beyond the line oftravel'of the jars under the influence of the pusher plate, the circuitthru contacts 92 and 98 is broken, whereupon the spring 56 returns thelug 53 to its ynormal position` and the engagement of the lug 67 uponthe lug 53 precludes further movement of the plunger plate and of thearms. Springs 83, 84 and 72freturn the arms 7 9 and 80 and plunger plate9G to their normal positions. In event that a second vj ar should bedischarged into the pocket 950 before the plunger plate has beenreturned to its normal position, the plates 90 will retain saidvjaruntil the plunger plate has been returned to its normal positionwhereupon the circuit embracing the electro magnet being closed, theparts will again function.
